[0014] Beneficial effects

[0015] The utility model provides a multi-roller offset leveling device for flame-retardant and high-temperature resistant woven fabrics. Compared with the existing technology, it has the following advantages:

[0016] 1. The multi-roller staggered leveling device for flame-retardant and high-temperature resistant woven fabrics is equipped with a heating component. The steam generator installed inside the steam box produces high-temperature steam, which is ejected through multiple sets of steam nozzles. The high-temperature steam is sprayed onto the surface of the flame-retardant and high-temperature resistant woven fabric.

[0017] 2. The multi-roller staggered leveling device for flame-retardant and high-temperature resistant woven fabrics drives the bidirectional screw to rotate by starting the tensioning motor. The rotation of the bidirectional screw causes the sliding blocks on both sides to slide synchronously to relative or opposite sides. The sliding of the sliding block causes one end of the rotating rod to rotate at the bottom of the sliding block, and the other end of the rotating rod to rotate at the top of the transmission plate, thereby causing the transmission plate, the transmission rod and the tensioning roller to slide downward or upward synchronously. By providing a tensioning mechanism and utilizing the drive of the tensioning motor, the height of the tensioning roller can be flexibly adjusted, and the tension degree can be flexibly adjusted during the transportation of flame-retardant and high-temperature resistant woven fabrics of different thicknesses. In addition, by adjusting the tension degree of the flame-retardant and high-temperature resistant woven fabrics, the leveling quality of the flame-retardant and high-temperature resistant woven fabrics can be further improved.

[0027] A buffer assembly 82 is provided on top of the screed 815;

[0028] The heating assembly 83 is arranged on the top of the conveying frame 4 .

[0029] The driving cylinder 812 is connected to the external air source through an air pipe; the winding roller 3 is driven to rotate by the motor, and a rotating wheel is installed on the surface of the synchronous motor output shaft, and the surface of the rotating wheel is connected to the transmission wheel through a transmission belt, and a rotating roller is installed on one side of the transmission wheel, and the conveyor belt 6 is sleeved on the surface of the rotating roller, so that the winding roller 3 and the conveyor belt 6 rotate synchronously; the piston rod slides inside the support plate 811.

[0030] In this embodiment, the buffer assembly 82 includes a buffer rod 821 installed on the top of the smoothing plate 815.

The top end of the buffer spring 822 is fixedly connected to the bottom of the connecting plate 813, and the bottom end of the buffer spring 822 is fixedly connected to the top of the smoothing plate 815.

[0034] Multiple groups of adjustment holes are installed on the surfaces of the supporting plates 831 on both sides for manually adjusting the heights of the multiple groups of steam nozzles 835 .

[0035] By providing a heating component 83, a steam generator installed inside the steam box 832 produces high-temperature steam, which is ejected through multiple groups of steam nozzles 835 to spray the high-temperature steam onto the surface of the flame-retardant and high-temperature resistant woven fabric.

In addition, the height of the flattening roller 816 can be freely adjusted by the provided driving cylinder 812, thereby being suitable for flattening flame-retardant and high-temperature resistant woven fabrics of different thicknesses.

[0036] In this embodiment, the tensioning mechanism 7 includes a tensioning motor 71 installed on one side of the conveying frame 4. One end of the output shaft of the tensioning motor 71 is fixedly connected to a bidirectional screw rod 72 through a coupling. The surface of the bidirectional screw rod 72 is threadedly connected to a sliding block 73. The bottom of the sliding block 73 is rotatably connected to a rotating rod 74.

The surface of the transmission rod 752 is slidably connected to the interior of the conveying frame 4, and the bottom of the transmission plate 751 is rotatably connected to the two ends of the tensioning roller 76.

[0039] The transmission rod 752 slides inside the conveyor frame 4 to limit the upward and downward sliding of the transmission plate 751 and the tensioning roller 76.

[0040] By starting the tensioning motor 71 to drive the bidirectional screw rod 72 to rotate, the rotation of the bidirectional screw rod 72 causes the sliding blocks 73 on both sides to slide synchronously to relative or opposite sides, and the sliding of the sliding block 73 causes one end of the rotating rod 74 to rotate at the bottom of the sliding block 73, and the other end of the rotating rod 74 rotates on the top of the transmission plate 751, thereby causing the transmission plate 751, the transmission rod 752 and the tensioning roller 76 to slide downward or upward synchronously. By providing the tensioning mechanism 7, the height of the tensioning roller 76 is flexibly adjusted under the drive of the tensioning motor 71, and the tensioning degree of the flame retardant and high temperature resistant woven fabrics of different thicknesses is flexibly adjusted.

[0041] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0042] During operation, the flame retardant and high temperature resistant woven fabric is first passed around the conveying roller 5, the leveling roller 816 and the conveyor belt 6, and one end of the flame retardant and high temperature resistant woven fabric is fixed on the surface of the winding roller 3. Then, the tensioning motor 71 is started to drive the bidirectional screw rod 72 to rotate. The rotation of the bidirectional screw rod 72 causes the sliding blocks 73 on both sides to slide synchronously to the relative or opposite sides, and the sliding of the sliding block 73 causes one end of the rotating rod 74 to rotate at the bottom of the sliding block 73, and the other end of the rotating rod 74 rotates at the top of the transmission plate 751, thereby causing the transmission plate 751, the transmission rod 752 and the tensioning roller 76 to slide downward or upward synchronously. By adjusting the height of the tensioning roller 76, the tensioning degree of flame retardant and high temperature resistant woven fabrics of different thicknesses can be flexibly adjusted during the transportation process. Then the steam box 832 is started to spray high temperature steam through the folding tube 833, the ventilation pipe 834 and the steam nozzle 835 to Warm steam is sprayed onto the surface of the flame retardant and high temperature resistant woven fabric, and the heat and humidity of the steam are used to make the fibers of the flame retardant and high temperature resistant woven fabric soft. Subsequently, as the conveyor belt 6 and the winding roller 3 continue to be pulled, the driving cylinder 812 is started to drive the piston rod, the connecting plate 813 and the connecting rod 814 to slide downward synchronously. The connecting rod 814 slides inside the support plate 811, and the sliding of the connecting plate 813 will cause the buffer rod 821, the buffer spring 822, the smoothing plate 815 and the leveling roller 816 to slide downward synchronously, and the flame retardant and high temperature resistant woven fabric is pressed by the leveling roller 816. Then, the flame retardant and high temperature resistant woven fabric is pulled by starting the winding roller 3. Synchronously, the conveyor belt 6 is driven to rotate synchronously by the rotating wheel, the transmission belt and the transmission wheel. In this process, when the heated flame retardant and high temperature resistant woven fabric slowly passes through the leveling roller 816, it will be restored to flatness under the pressure of the leveling roller 816.
